Amazon offers the Mobil 1 M1-110 Extended Performance Oil Filter for $9.99. (Advance Auto Parts charges the same via pickup.) Plus, Prime members receive free shipping. (Non-members can spend $35 or more to qualify for free shipping; otherwise, it adds $5.58.) That's the lowest total price we could find by $10. It purportedly holds up to twice the amount of contaminants as other filters and prevents dry-starts.
